A Comparison of DMS Workflows Scheduling Concepts
Keywords:Workflow Scheduling, Workflow Management System, Grid Computing, Distribution Management System
AbstractThe development of computational and communication technology enabled an introduction of a Distribution Management System (DMS) as a sophisticated approach to solve various problems regarding the power supply in modern society. These advanced systems execute a large number of workflows to meet requirements and provide desirable functionalities. Very high demands for computational resources during the DMS operation, imposed a necessity for an adequate DMS workflow management. Three DMS workflow scheduling concepts (architectures) are presented in this paper: centralized, mixed and hierarchical. These scheduling concepts are compared by different parameters such as performance, scalability and complexity of implementation. The conducted experimental study showed that the hierarchical scheduling concept not only provides the best performance, but also is the most scalable and entirely eligible in terms of implementation complexity.
